HARRY A. MASSEY, OF EAST ST. LOUIS, ILLINOIS, ASSIGNOR 0E ONE-HALF TO GEORGE E. STEIN, OF ST. LOUIS, MISSOURI.

ROTARY ENGINE.

To all whom it may concern:

Be it known that I, HARRY A. Massey, a citizen of the United States, and resident of East St. Louis, St. Clair county, Illinois, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in rotary engines, the object of my invention being to construct an engine of the rotary type in which there is a cylinder formed by a shell and a piston carrier, there being an integral piston formed on the piston carrier, the forward face of the piston being formed tangentially relative to the piston carrier and arranged to actuate in its rotation an abutment which is spring actuated in opposition to the piston, thereby dispensing with the usual extraneous apparatus for operating abutments of this type.

For the above purposes my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims and illustrated by the accompanying drawing, in which:

Figure 1 is a longitudinal, sectional elevation of the complete engine; and Fig. 2 is asectional elevation of the complete engine taken at right angles to Fig. 1.

Referring by numerals to the accompanying drawing: 1-1 designate the cylinder heads each of which is provided with integral standards 2, integral bases 3, and formed integral with each base and standard is a bearing a.

A cylinder ring 5 is positioned between the heads 1-1 and is held in place by the cap screws 6, and formed integral with the lower portion of the ring 5 are enlargements 77, one of which is provided with an inlet port 8 and the opposite one with an exhaust port 9 in communication respectively with the steam pipe 10 and exhaust pipe 11. Formed integral with the ring 5 is an exten sion 12 extending a width greater than the space between the heads and having its ends seated in the heads, through which extension is formed an opening of a width equal to the distance between the heads.

An abutment 13 is arranged for movement through the opening formed in the ex- Specification of Letters Patent.

tension 12 and carried by the abutment are arms 14 projecting laterally from each face of the abutment adjacent its lower end, and carried by each arm is an I-bolt 15 having an adjusting nut 16. springs 17, having their one end connected with the I-bolt and their other end with an eye carried by the ring, provide means for normally holding the abutment elevated.

Each of the heads 1 is provided with a stufling-box 18 through which is inserted a shaft 19 which is supported in the bearings 4, and supported by the shaft 19 and secured to it against rotation is a piston carrier 20 having formed integral therewith a piston 21 arranged to conform in shape and size with the space between the carrier 20, the ring 5 and the heads 11, which space is preferably rectangular in cross section.

The rearmost face 22 of the piston is preferably formed on a radial line relative to the carrier 20 and the forward face 23 of the piston is formed on a line tangent relative to the carrier 20, the upper face of the piston is recessed to form a seat for a packing plate 2% and is further provided with a pocket 25 in which is seated an expansive-coil spring 26 arranged to normally hold the plate 2& in engagement with the inner face of the cylinder ring 5.

In practical operation the steam is admitted through the pipe 10 and port 8 between the abutment 13 and face 22 of the piston, thus rotating the piston and carrier 20.

It is to be noted in this connection that the admission of steam is constant. A continued movement of the carrier 20 and piston will bring the face 23 of the piston into a position engaging the abutment, and, by reason of the inclined face of the piston the abutment will be depressed permitting the piston to move past the abutment. As the piston is brought to a position covering the port 8 the steam from the pipe 10 will be cut 03 and that portion of steam in the cylinder in advance of the piston will exhaust through the port 9 and exhaust pipe 11.

I claim:

1. In a rotary engine, the combination with a casing and piston carrier coacting to form a cylinder, a piston having an inclined forward face carried by the carrier, a spring actuated packing plate pivotally mounted on the piston, a steam inlet and a steam exhaust,

Contractile coil an abutment betWeen said inlet and exhaust arranged to be actuated in one direction by the forward face of the piston. laterally projecting arms carried by the abutment, springs connecting said arms and said casing and means for varying the tensionnof said springs.

2. In a rotary engine, the combination With a casing and a piston carrier coacting to form a cylinder, a piston, formed integral with said carrier, having an inclined for- Wv'ard face, a packing plate arranged on the periphery of the piston and means for normally holding the packing plate in engagement with the casing, a steam inlet and a steam exhaust, an abutment arranged between said inlet and exhaust, springs for normally holding the abutment in engagement with the piston and carrier and means for varying the tension of said springs.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

HARRY A. MASSEY.
